Fig. 1 illustrates to comprise interior environment system 18 according to the railway vehicle 10(of example) the general profile chart of structure, the arrow in Fig. 1 represents the flowing of air.As shown in Figure 1, railway vehicle 10 has the interior environment system 18 on the vehicle body 12 and the multiple seats 16 be arranged in the floor 14 of compartment S1 that possess the compartment S1 holding passenger and the top loading vehicle body 12.
As shown in Figure 1, interior environment system 18 possesses the sucking hole 22 of the roughly quadrangle on the overall width direction central portion in the roof face 20 being arranged at compartment S1, the suction lead 24 with the cross section of roughly quadrangle arranged with extending upward from sucking hole 22, the housing 28 arranged highlightedly upward from the covering for roofs 26 of vehicle body 12 and extends in the longitudinal direction in the rear side in the roof face 20 of compartment S1 and two the roof conduit 30(Fig. 1 arranged across compartment of terrain in the lateral direction, the roof conduit 30 in left side be only shown).
As shown in Figure 1, housing 28 is formed as the structure of roughly basket shape, and the inner space of housing 28 is divided into than partition wall 32 near the first Room S2 at rear with than the second Room S3 of partition wall 32 near front by partition wall 32.And, be formed in a return air inlet 34 and two return air outlet 36(Fig. 1 in the bottom surface of the first Room S2 and only illustrate one), return air inlet 34 is connected with the upper end of suction lead 24, and each return air outlet 36 is connected with one corresponding in two roof conduits 30.Again, be formed with the outer gas entrance 38 introducing outer gas in the side of the second Room S3 and discharge and export 40 from the outer gas of the outer gas of outer gas entrance 38 introducing.
As shown in Figure 1, a roof conduit 30 is configured on the left side of suction lead 24 in overall width direction, and another roof conduit 30 is configured in the right side (diagram is omitted) of the suction lead 24 in overall width direction.And, on the roof face 20 of the compartment S1 on each side in two roof conduits 30, the blow-off outlet 42 of the slit-shaped that fore-and-aft direction extends is formed along corresponding roof conduit 30, and blow-off outlet 42 and the roof conduit 30 corresponding with it are communicated with by communicating passage (diagram is omitted).
Again, as shown in Figure 1, interior environment system 18 possesses: the suction grid 50 being arranged at sucking hole 22; Be configured in the first Room S2 of housing 28, sucked the indoor blower 52 of air by suction grid 50 from sucking hole 22; Be configured in the downstream of suction grid 50 and the upstream side of indoor blower 52, rectification is by the rectification part 54 of the air of suction grid 50; Be configured in the second Room S3 of housing 28, introduce outer gas from outer gas entrance 38, and by outdoor blowers 56 that this outer gas is discharged from outer gas outlet 40.In addition, interior environment system 18 possesses the control part (diagram is omitted) of the temperature booster 60 that is configured in the first Room S2 and evaporator 62, the compressor 64 being configured in the second Room S3 and condenser 66 and control heater 60 and compressor 64.Therefore, in interior environment system 18, form the return air stream R1 being back to compartment S1 from compartment S1 after suction grid 50, rectification part 54, evaporator 62, temperature booster 60, indoor blower 52, roof conduit 30 and blow-off outlet 42.Again, the outer air-flow road R2 being back to outside S4 from the outside S4 of housing 28 after outer gas entrance 38, condenser 66, outdoor blowers 56 and outer gas outlet 40 is formed.And, drive compressor 64 by control part (diagram is omitted), can cool by evaporator 62 return air flowed in return air stream R1 with this, or, drive temperature booster 60 by control part (diagram is omitted), can heat by temperature booster 60 return air flowed in return air stream R1 with this.
Fig. 2 is the general profile chart of the structure of the important part that interior environment system 18 is shown, Fig. 3 is the upward view of the structure that suction grid 50 is shown.Again, Fig. 4 and Fig. 5 is the general profile chart of the structure that suction grid 50 and rectification part 54 are shown.As shown in Figures 2 and 3, suction grid 50 is arranged on sucking hole 22 to block the sight line of passenger etc., and has and mutually in the longitudinal direction to extend on overall width direction and covering component 72 on the central portion of the multiple grizzly bars 70 mutually configured substantially in parallel and be configured in fore-and-aft direction on overall width direction sucking hole 22 with extending across interval.Again, as shown in Figure 4, suction grid 50 has the suction face 74 of the end of the suction side being positioned at multiple grizzly bar 70.Suction face 74 is imaginary planes of the end of each suction side comprised in multiple grizzly bar 70, is the reference plane when specifying following tilt angle alpha, β as benchmark.
As shown in Figure 4, each in multiple grizzly bar 70 to have from suction face 74 configure successively towards the downstream of air flowing, the hang plate portion 76 that tilts relative to suction face 74, and to be formed continuously from hang plate portion 76 and relative to sucking face 74 to roughly orthogonal direction and to the current plate portion 78 of downstream extension.As shown in Figure 2, in this example, the multiple grizzly bars 70 being configured in the front of blocking component 72 are opposite each other with the direction of tilt in its hang plate portion 76 of multiple grizzly bars 70 being configured in rear, the each hang plate portion 76 be configured in multiple grizzly bars 70 in front to be formed as the closer to suction face the structure that 74 are located front, and each hang plate portion 76 be configured in multiple grizzly bars 70 at rear to be formed as the closer to suction face the structure that 74 are located rear.
As shown in Figure 5, relative to the angle [alpha] in the current plate portion 78 in suction face 74 scope (70 degree≤α≤110 degree) that to be positioned at 90 degree be benchmark ± 20 degree, most preferred angle [alpha] is positioned at 90 degree for benchmark ± 5 degree scope (85 degree≤α≤95 degree).When angle [alpha] is significantly away from 90 degree, the direction of rectification air can not be made consistent with the direction that suction lead 24 extends, be difficult to the flowing of stable air.Again, when angle [alpha] is significantly away from 90 degree, the flowing of air is coupled with horizontal composition and flow velocity increases, the airflow noise produced when air touches rectification part 54 can increase.
As shown in Figure 5, be more than 25 degree and less than 55 degree relative to the inclination angle beta in the hang plate portion 76 in suction face 74.When inclination angle beta is less than 25 degree, in the boundary portion 82 in current plate portion 78 and hang plate portion 76, produce eddy current in air stream, airflow noise can increase.Again, when inclination angle beta is greater than 55 degree, need the spacing p reducing grizzly bar 70 in order to hide, therefore the number of grizzly bar 70 increases, and weight and cost improve.
As shown in Figure 4, using the length in each direction orthogonal with sucking face 74 in multiple grizzly bar 70 as D time, the length d1 in the party current plate portion 78 is upwards more than 0.35D and below 0.65D.When the length d1 in current plate portion 78 is less than 0.35D, the rectification effect in current plate portion 78 can not be given full play to.Again, when the length d1 in current plate portion 78 is greater than 0.65D, the length d2 in hang plate portion 76 shortens, and therefore needs to reduce the spacing p of grizzly bar 70 to give full play to the effect of blocking sight line in hang plate portion 76.In this case, the number of grizzly bar 70 can increase, and weight and cost can improve.
As shown in Figure 4, on every side in the front and rear of blocking component 72, using a grizzly bar 70 in two grizzly bars 70 adjacent one another are forming multiple grizzly bar 70 as the first grizzly bar, another grizzly bar 70 of 74 sides tilted to suction face, hang plate portion 76 of the first grizzly bar will be positioned at relative to the first grizzly bar as the second grizzly bar.When both planes of the downstream ora terminalis 70a that will comprise in the first grizzly bar and upstream side ora terminalis 70b are as imaginary reference plane 80, being positioned at least partially than imaginary reference plane 80 on the position of the first grizzly bar side of the current plate portion 78 in the second grizzly bar and the boundary portion 82 in hang plate portion 76.That is, interval (spacing) p of two grizzly bars 70 adjacent one another are is designed to being configured at least partially than imaginary reference plane 80 on the position of the first grizzly bar side of boundary portion 82.Again, as shown in Figure 2, blocking component 72 being configured on the gap Q between the grizzly bar 70 in its front and configuration grizzly bar 70 is in its rear formed as having the roughly shaft-like can guarantee aeration and block sight line of the cross section of general triangular.Therefore, can't see than the inner structure of suction grid 50 near the inside from compartment S1.
As shown in Figure 4, spacing p is preferably formed as far as possible significantly in the scope not affecting the effect of blocking sight line.That is, when spacing p is less, the number of grizzly bar 70 increases and suction grid 50 aperture area reduces, and the flow velocity obtained needed for same traffic increases.Six powers of airflow noise and flow velocity increase roughly pro rata, and the quadratic power of loss of pressure and flow velocity increases roughly pro rata, therefore in order to reduce airflow noise and loss of pressure, preferably increase spacing p as far as possible.Therefore, in this example, meet the patten's design spacing p of the relation of " p > 4t " with the thickness t and spacing p that make grizzly bar 70.
As shown in Figure 4, rectification part 54 has the function of dust contained in the function of the flowing of rectification air and traps air simultaneously, and in this example, the air filter with the multiple holes making air pass through uses as rectification part 54.Rectification part 54 is configured in the downstream of suction grid 50 and on the upstream side of indoor blower 52, the first type surface 54a of the upstream side of rectification part 54 is almost parallel relative to suction face 74 and generally perpendicularly configure relative to current plate portion 78.As shown in Figure 4, using the length in each direction orthogonal with sucking face 74 in multiple grizzly bar 70 as D time, the interval H of the first type surface 54a of the end face 50a in the downstream of suction grid 50 and the upstream side of rectification part 54 is more than 0 and below 2D.When this interval H is greater than 2D, between the end face 50a in the downstream of suction grid 50 and the first type surface 54a of the upstream side of rectification part 54, the direction of air stream easily changes, and fully can not suppress the generation of airflow noise.
As shown in Figure 1, when driving indoor blower 52, the air of compartment S1 is sucked from sucking hole 22 by suction grid 50, and this air is back in compartment S1 after rectification part 54, evaporator 62, temperature booster 60, indoor blower 52, roof conduit 30 and blow-off outlet 4.As shown in Figure 5, in the process of air by suction grid 50, can not increase horizontal composition to the flow velocity u1 of this air, the flow velocity u1 of the air on the entrance of suction grid 50 is identical with the flow velocity u1 of the air in the outlet of suction grid 50.
[effect of example]
According to the railway vehicle 10 of this example, by possessing interior environment system 18, following effect can be played with this.
As shown in Figure 5, can the flowing of rectification air by each current plate portion 78 in multiple grizzly bar 70, and the generation of the airflow noise caused due to the direction change of the flowing of air can be suppressed.Again, current plate portion 78 is roughly extended on orthogonal directions relative to suction face 74, therefore the flow velocity u1(Fig. 5 to the air flowed along current plate portion 78 can be suppressed) increase horizontal composition, the generation of the airflow noise caused because of the increase of flow velocity can be suppressed.
Fig. 6 is the general profile chart illustrated according to the suction grid 90 of comparative example and the structure of rectification part 92.According in the suction grid 90 of comparative example, angle [alpha] and inclination angle beta are designed to 34 degree, and grizzly bar 96 is bent into 68 degree in boundary portion 94.In this comparative example, in the process that air flows along current plate portion 98, increase horizontal ingredient u 2 to the flow velocity u1 of air, the flow velocity u3 of the air therefore contacted with rectification part 92 becomes greatly (u3 > u1), and the airflow noise produced when air contact rectification portion 92 becomes large.Again, produce eddy current (illustrating with arrow in Fig. 6) when air bends largely in boundary portion 94, the airflow noise therefore produced in boundary portion 94 becomes large.As shown in Figure 5, according in the suction grid 50 of this example, relative to the angle [alpha] in the current plate portion 78 in suction face 74 scope that to be positioned at 90 degree be benchmark ± 20 degree, therefore can suppress the situation flow velocity u1 of air being increased to horizontal composition, the generation of the airflow noise in rectification part 54 can be suppressed.Again, the generation of the eddy current in boundary portion 82 can be suppressed, thus the generation of the airflow noise caused because of eddy current can be suppressed.
The personnel such as contriver are about the suction grid 50(Fig. 4 according to this example), be set to D=22mm, H=23mm, d1=11mm, p=9.5mm, α=90 degree, β=34 degree, and suction grid 90(Fig. 6 about according to comparative example), be set to D=22mm, H=23mm, d1=11mm, p=16.6mm, α=34 degree, β=34 degree, and compare the experiment of the size of airflow noise.Can confirm that suction grid 50 is compared with suction grid 90 by this experiment, higher than the fact that the frequency of 500Hz significantly can reduce airflow noise.
As shown in Figure 4, be more than 25 degree relative to the inclination angle beta in the hang plate portion 76 in suction face 74, therefore can suppress the generation of the eddy current in boundary portion 82, the generation of the airflow noise caused because of the generation of eddy current can be suppressed.Again, inclination angle beta is less than 55 degree, therefore in order to block the spacing p that can increase grizzly bar 70, and can realize lightweight and cost degradation by the quantity reducing grizzly bar 70.
As shown in Figure 4, each hang plate portion 76 in multiple grizzly bar 70 tilts relative to suction face 74, therefore can block sight line by hang plate portion 76, can guarantee to be difficult to see the inner structure more inner than suction grid 50 from the upstream side of suction grid 50.Especially, in this example, in adjacent two grizzly bars 70, being positioned at least partially than imaginary reference plane 80 on the position of the first grizzly bar side of the current plate portion 78 of the second grizzly bar and the boundary portion 82 in hang plate portion 76, it is hereby ensured from the upstream side of suction grid 50 and can't see the inner structure more inner than suction grid 50 completely.
As shown in Figure 2, the first type surface 54a of the upstream side of rectification part 54 is almost parallel relative to suction face 74 and generally perpendicularly configure relative to current plate portion 78, therefore when air is supplied on this first type surface 54a, can suppress to increase horizontal composition to the flow velocity of air, thus the direction change etc. because of the raising of flow velocity and the flowing of air can be suppressed and the generation of the airflow noise caused.And, use air filter as rectification part 54, therefore do not need to arrange rectification part 54 and other airfilter respectively, whole equipment miniaturization can be made, and can maintenance activity be improved.
As shown in Figure 4, using the length in each direction orthogonal with sucking face 74 in multiple grizzly bar 70 as D time, the length d1 in the party current plate portion 78 is upwards more than 0.35D and below 0.65D, therefore can give full play to the rectification effect in current plate portion 78, and the effect of blocking sight line in hang plate portion 76 can be given full play to.
As shown in Figure 4, the interval H between the first type surface 54a of the end face 50a in the downstream of suction grid 50 and the upstream side of rectification part 54 is more than 0 and below 2D, and therefore the direction of air stream is difficult to change between which, fully can suppress the generation of airflow noise.
[other examples]
As shown in Figure 3, in above-mentioned example, the multiple grizzly bars 70 forming suction grid 50 are arranged at intervals in the longitudinal direction, but as shown in Figure 7, in other examples, also the multiple grizzly bars 70 forming suction grid 50 can be arranged at intervals in the lateral direction.
Again, the direction in the hang plate portion 76 of suction grid 50 is symmetrical relative to blocking component 72, but is not limited to this, also all hang plate portions 76 can be configured to equidirectional.In this case, also can not arrange and block component 72.
As shown in Figure 1, in above-mentioned example, although show the vehicle travelled in orbit, various railway vehicle and bus, other the vehicle etc. also can be applied to.Again, in other example, also can replace rectification part 54 and the filter of the function only having the rectification part of rectification function and only have trap debris is set independently.The metal gauze etc. with multiple hole can be used as such rectification part.
